When designing a WLAN to support voice in a large office, which design element is of the highest concern for performance?

• A.AP vendor
• B.Frequency Selection
• C.Band steering
• D.Roaming

Switches and APs have already been chosen by your customer. All switches support 802.3bz MultiGig interfaces and APs are 4x4:4 802.11ac wave 2 capable of using dual-5GHz and have one MultiGig interface.
Some cable drops for the APs will run for more than 180.5 feet (or 55 meters). To support MultiGig, what is the best choice of cabling?

• A.Cat-6
• B.Cat-5e
• C.Cat-5
• D.Cat-6a

When surveying an existing WLAN infrastructure for a possible redesign, you use two Wi-Fi USB adapters to collect RSSI data and two USB spectrum analysis adapters to collect RF spectrum data. Since your laptop doesn't have enough USB ports, you use a 4-port powered USB 3.0 hub. What issues could be caused by the use of USB 3.0 that will impact your site survey?

• A.It generates noise in the 2.4 GHz band, giving you a false perception of the noise floor.
• B.It generates noise in the 5 GHz band, giving you a false perception of the noise floor.
• C.It does not give you enough power for all four of your adapters.
• D.It does not give you enough bandwidth to collect data coming from all of the adapters.

A customer is acquiring a new VoWLAN system to replace their existing wired phone system. When reading about his system's requirements, you learned that is requires 25 db of SNR to work as expected. After surveying the environment, you discovered that the noise floor is -88 dBm. What should be the minimum RSSI value to meet the system's requirements?

• A.-65 dBm
• B.-67 dBm
• C.-63 dBm
• D.-70 dBm

What limitation exists when WMM is not enabled on an 802.11n WLAN?

• A.802.11 QoS will not be available
• B.Only two ACs will be available
• C.EDCA values will change
• D.The maximum channel-width will be 20MHz
